14. GMC Jimmy
GMC introduced the Jimmy as a mechanically identical car to the Chevrolet Blazer. However, the GMC Jimmy was still different thanks to the better-looking front end. Also, it had a bit more equipment and all-wheel drive came as standard. From the start, they intended the Blazer for a wide audience. But they also aimed the Jimmy towards the off-road enthusiast market. And that is why the GMC Jimmy is rare. The most popular versions are the early ones from the late ’60s and early ’70s.

The engine lineup started with straight-six, but most buyers opted for the more powerful V8 engines. Just like the Blazer, the GMC Jimmy had a removable hardtop. These are the classic vehicles before those plastic SUVs took over. In fact, they are the best American off-road trucks they ever made. And although most SUV fans would like to see them return, they want them to retain their sturdy and rugged features.
